T60 will not switch on.

[karotlopj]

I have a ThinkPad T60 (TYPE 1953-DAU) which displays the mains indicator light when the charger is attached. When there is a battery the charging indicator blinks as though charging, but when I press the power switch the lights go out.

Any ideas on what's wrong?

Most likely a bad/dead battery.
Remove it, then try to boot from the mains.

I tried to make it clear that when it's connected to the mains the mains indicator light is on, whether there is a battery inserted or not, and that in either case, when pressing the power switch the lights go out.

A couple of suggestions:

1) Reseat the RAM, try booting with only one stick at the time. If that doesn't work...

2) Remove all the RAM, try powering the system on. Does it beep?

Leave the battery out of the machine while performing all of the above.

Good luck.

One more option: remove battery and charger, then press and hold down the power button for ~20 seconds for a hard reset.
Then try to boot from only charger.

(The above does the same as the popular "press/hold 10 times for a few seconds, then press/hold for 30 seconds"!)

If that fails, also remove the CMOS-battery for a minute, reinsert and try again.

There is no ram. Should it beep when I try powering on?

As soon as I press the power switch the mains light goes off.

Yes. It should beep 1-3-3-1, and get to a blank screen.

You can try swapping the CPU if you have another, but that's pretty much a stretch...realistically speaking, your motherboard is likely bad.

I've been through this cycle previously with another T60... Looking on ebay, this seems to be common problem

Was working perfectly up to a couple of months ago, then had to turn it on and off a couple of times before it would to work.

It doesn't start up at all now, the battery charging light shows on when charger is plugged in, but when you press the on button it goes off.

Last time I tried to get a replacement for a different T60, I realised there were a large number of different motherboards. How do I find out which to get? ie where is the MB P/N?

As long as it's not from a widescreen (15.4") model, any T60/p board will fit.

Mine is a 15" model (TYPE 1953-DAU), and I know from experience thay they are all the same....I'll try and find my thread from last year when I went through the same process.

[karotlopj]

ooops... thay they are NOT all the same.

How's that?

The only difference between a standard (4:3) 14" and 15" models is that the latter requires an interposer card, but that's not a part of a motherboard and you already have it on your machine.

You'd need a different heatsink for an ATi-powered board, but that's it.

This matter has been discussed ad nauseam, let's not re-hash it, no need for that. The science has been settled on that one a long time ago.

It might fit, but that's not the point. The original motherboard (41W1362) in my T60 had a PCIe slot behind the audio sockets. The replacement I got (42T0116) did not, so I couldn't use it.

FYI: all 4:3 T60/p planars have the mini PCIe slot (the one that is used for the wireless card) in the same spot. Some of them have another slot enabled for WWAN. The first one is in the middle of the planar - for a lack of a better description - while the second one is more to the left, almost bordering the frame.

I have no idea what went wrong with your intended swap, but having worked on hundreds of T60/p units I'll just state that I have never encountered any similar issues.

The replacement MB (42T0116) does not have a PCIe slot behind the audio ports just above the PCMCIA housing. Maybe I was just unlucky stumbling on this MB...

I feel your pain, just make sure nimbers line up before you buy. Got a W700 board to find out it wouldnt work with my components. Only some beepcodes. Not to mention the seller damaged the board. I went back after getting a refund and bought the matching board and it worked well.

In the T60 HMM the mobos with description "with wireless WAN" have that second PCIe slot you are looking for.
Unless you use WWAN, you don't need it and it has no influence on the mobo's functionality.

My guess is you got a dud.

Thanks for pointing that out. I may try re-assembling using the replacement motherboard and just leaving the WWAN card loose. Incidentally, I just thought that if there is a WWAN card here ought to be a SIM card slot.... and looking round I just spotted it... never noticed before.
